Watch screwdriver sharpening jig

prusaprinters

Being disappointed in the lack of printable screwdriver sharpening jigs and time it takes to ship one from China – I made my ownThis model accepts screwdrivers up to 6mm in diameterSide screw allows easy flipping to sharpen evenlyUse 608 bearings (usual skateboard or fidget bearings)Polygonal axis allows easier bearing installationUse at least 20mm M3 screw (25mm on photo) to clamp your screwdriver from the side Printing:There are 4 models with different size of bearing axis (8.0, 8.1, 8.2 and 8.3mm)I use 8.3mm one, but it requires pressing bearings on with some forceIf you want – print ScrewdriverSharpeningJig_FitTest and testfit your bearing before printing the main model (if the polygon with “1” on it is still tight – print the 8_0 model)Print standing up with a big brim (see slicer screenshot)I used 0.2mm layers and 3 perimetersInfill doesn't really matter, so 15% is fine, for exampleNo supports are required
